i T 0 all whom it may concern:

' Be it known thatLJosnr B AUTIGAM, a

subject of Germany, and a resident of the county of Kings, borough of Brooklyn, city, and State of New York (whos'e post-ofiicef address is, 4584- lilststreet, Brooklyn, New York), have invented a new and useful Au-.

tomobile Accelerator, of; which the following is such a full, clear, andexact descrip- 7 to which it appertains to make anduse the I 1 same, reference heinghad to the acc'ompanyf ,ing drawing, which forms part of this ap tionas will enable anyone skillcdin the art lphcation.

This invention relates to automobile .ac-"

c'elerators and especially to that type which may be readily attached to automobiles otherwise unprovided therewith.

pi'ovision of simple and efficient means readily attachable to an automobile not ordinarily adapted therefor, for pedally regulating the opening of the throttle valve of I which does not interfere with the manually v vention, the bell-crank lever 10, having'the manipulated throttle connection.

For the accomplishment of the aforesaid and other objects as will appear from the description which follows, I employ the de-. vice shown in its preferred form in the accompanying drawings, in which- I Fig. 1 is a side view of my improved device as it appears attached to the throttle lever of a Ford car. n

Fig, 2 is a plan view of the same.

Fig. 3 is a front view of one of. the bellcrank levers used in connection with my device, and

Fig. i is a perspective view of thebolt for supporting the device. c

In the illustrated embodimentof my inpreferably cylindrical ends 11 and 12, is mounted for oscillatory movement on the pin 14, which projects from the head of the bolt 13 substantially at right angles to the shank of said bolt. The said bolt-13 is adapted to replace one of the bolts of the One of the objects of, this invention is the crank; case 5.15 is suitably threaded for that purpose. For supportingv a suitable push button ofthe usual type adapted to be operatedby the foot ofthe driver, the rod 16, bent to spring said buttoninto the desired position,-is passed through. a suitable hole in thefloor board 17, one extremity of said rod being bent at substantially right bell-crank lever 10. v 1 .A second bell crank lever 18, having the split hub 21 thereon, has the preferably cyqliIud'ricztl ends '19 and 22thereof apertured to receive the rods 28 and 23 respectively "as will be more fully described hereinafter,

said lever l8 being adapted c. to be loosely mountedon the usu'alllthrottle "lever 27. In that form fofmv device especially; adapted for use in the Ford'make of automobiles, :pro ect1ng p1n'20 lsprovided on that arm of the lever 18 which carries the end 19, the pin 20 outstanding into the path ofthe throttle lever crank 26-on thethrottle lever 27, which crank and lever formpart of the throttle valve operating mechanism of a Ford car. That end of the throttle operating rod 28 which is usually connected to .the crank 26 is removed therefrom and inserted'instead into the opening of the end 19 of the lever 18, a tension spring 25 serving to flexibly connect said rod 28 to the end 12 t of, the lever 10. The rod 23, provided with the turnbuckle24 for the adjustment of the pressure of thepin 20 on the crank 26 and for the adjustment of the foot push button, connects the end 22 of the lever 18with the end 12 of the lever 10. i

The operation of my improved device is as follows:

Foot pressure on the accelerator button causes the bell-crank lever 10 to rotate in the direction of the arrow in Fig. 1 whereby the rod 23 is caused to move in the direction the. bell-crank lever 18.

does not cause said throttle lever torotate,

but instead moves the rod 28 to operate the throttle valve; The usual hand operation 'of the throttle levei'27 is not interfered with, since rotation of. said lever in angles'to the body thereof in order to pass "through the opening the and the the proper direction to open the carburetor throttle causes the crank 26 to engage the pin 20 and moves the bell-crank lever18 throttle lever.

by means of said pin in the proper direction to actuate the rod 28. Movement of the lever 27 in the direction operative to close the throttle Withdraws the crank 26 from contact with the pin and allows the spring to rotate the bell-crank lever 18 and therethrough to operate the throttle rod 28. V

It Will be seen that the spring 25 tends to maintain the pin 20 in contact with the crank 26 whereby release of the accelerator button merely closes the throttle to a position determined by the angular position of the hand throttle lever 27 on the steering column of the car, and that pressure on said button to open the throttle merely removes the pin 20 from contactavith the crank 26 and can cause :no movement ot' the hand I It will also be seen thatin its adaptation to Ford cars, my device utilizes the equipment already provided for the operation of the throttle valve. and may be quickly and easily attached Without disturbance of the ordinary operation ofany of the parts.

I claim: a

1, In combination with the hand throttle lever and the throttle lever crank of an aucase bolt, a pin projecting from said bolt, a bell crank lever loosely mounted on said pin, a foot push button connected to one end of said bell-crank lever, a second bell-crank lever loosely mounted on said throttle lever, a pin on said second bell-crank lever interposed in the path of said throttle lever crank, means for connecting said second bellcrank lever to the throttle valve of the carburetor, and means for normally maintaining said bell-crank lever pin in contact with said throttle lever crank. i y y 2. In combination with the hand throttle lever, the throttle lever crank and the throt- 'nected to one end of said bell-crank lever,

a second bell-crank lever loosely mounted on sa d hand throttle lever, a pin 'on said second bell-crank lever arranged 1n the path of said throttle levercrank, and an adjust-4 able'rod operatively connecting said bell crank levers and means for normally maintaining said pin in contact with said throttle lever crank;
